Abstract

I will propose an on-chip dark matter search, sensitive to dark matter candidates with masses corresponding to optical and near-IR energies. Certain dark matter candidates, such as axion-like particles, can convert into photons within an appropriately designed optical structure. We consider an array of periodically-structured resonators which host dark matter to photon conversion. These photons are then collected and directed via waveguides onto single photon counters with low dark count, such as individual skipper CCD pixels. This setup allows a high collection efficiency, and is scalable to large resonator counts to increase both the total conversion rate and the dark matter mass sensitivity. A key challenge is to optimally combine many weak, phase-incoherent signals from these resonators onto one detector, which we address with free-space, spatial power combining and a detector covering a large solid angle. This search is able to probe both QCD axion dark matter and dark photons with mixing down to 1e-15.
